Sternbergia

Am I mistaken? Sternbergia lutea here is an autumn bloomer. It is native
herein Israel and I will be on the lookout for seed. I wonder if the ones
I planted are actually from native stock or if they made the "great circle
route" and are imported by the nursery trade from Holland?

Dear Jim ,Thanks for your information. I am very familiar when you have a
self sterility problem with certain flowers. As a retired grower once I
know once other growers find a clone of something that grows well and has
some
good qualities growers will just multiply that clone.The problem is losing
genetic diversity. One disease can wipe out a susceptible clone and then it
is gone, maybe forever.-Russ H.

Another possibility is that we are seeing one single clone making up the
commercial stock of Sternbergia. It is probably self-sterile, as many
other plants in the Amaryllidaceae are. All you might need to get seeds
would be some live pollen from a different clone of the same species.
Another problem is that S. lutea occurs as triploid (2n = 3x = 33) as well
as the diploid (2n = 22) form. Triploids are usually sterile. See:

I would guess that you will have to find seeds of the diploid form, from
one of the seed exchanges or from someone like the Archibalds. Good
luck!

Russ, Sternbergia does not set seed. It is something to do with diploid
or whatever. Do you have one which does set seed, as there is a seed
setting one. But the most often grown one does not set seed.
